We have been using HDP on USP-V for some time and have a number of Pools in use. Thinking about when to close off a Pool and start a new one and when to just keep adding RGs.

Bigger Pools mean more opportunity to over subscribe and wider backend for performance, but at some point the risks of Pool faults due to maladministration or "double disk" failures in the underlying RGs come in to consideration.

Or do they, maybe we keep going until we have one massive Pool per disk media type.

Interested to know what others in the forum think ?
